In another embodiment, the invention discloses pharmaceutical compositions comprising such MCH antagonists as well as methods of using them to treat obesity, metabolic disorders, eating disorders such as hyperphagia, and diabetes.

REFERENCE TO RELATED APPLICATIONS

This application claims priority to U.S. Ser. No. 10/100,840 filed on Mar. 19, 2002, which.claims the benefit of U.S. Provisional Application No. 60/277,584, filed Mar. 21, 2001.

BACKGROUND OF THE INVENTION

This invention relates to antagonists for melanin-concentrating hormone (MCH) and their use in the treatment of metabolic and eating disorders.

MCH, a cyclic peptide, was first identified over a decade ago in teleost fish where it appears to regulate color change. More recently, MCH has been the subject of investigation for its possible role as a regulator of eating behavior in mammals. As reported by Shimada et al., Nature, Vol. 396 (17 Dec. 1998), pp. 670-673, MCH-deficient mice have reduced body weight and leanness due to hypophagia (reduced feeding). In view of their findings, it was suggested that antagonists of MCH action may be effective for the treatment of obesity. U.S. Pat. No. 5,908,830 discloses a combination therapy for the treatment of diabetes or obesity involving the administration of a metabolic rate increasing agent and a feeding behavior modifying agent, an example of the latter being an MCH antagonist.

Compounds of formula Ia wherein X¹ is CH, X³ is O, and Ar is 1,4-phenylene are prepared according to the method described in scheme 1:

N-Boc ketone 1, easily prepared from the N-TFA precursor (the synthesis of which is described in WO98/05292 for m=n=1) via standard TFA-removal with potassium carbonate in methanol/water followed by N-protection with di-tert-butyldicarbonate, is subjected to Wittig olefination, followed by hydroboration and oxidation to afford alcohol 3. Suzuki coupling on alcohol 3 with arylboronic acid R—B(OH)₂ followed by treatment of the biaryl alcohol intermediate with isocyanate R²—NCO give biaryl carbamate 4. This biaryl carbamate 4 is treated with TFA to remove the Boc-protecting group, and the resulting amine is further functionalized via reductive amination with an appropriate aldehyde or ketone, nucleophilic displacement with an alkyl- or aralkyl-halide, acylation with an acyl halide or sulfonation to provide biaryl carbamate Ia. Alternatively, the sequence of steps in Scheme 1 can be modified so that the Suzuki coupling reaction occurs after the condensation with the isocyanate R²—NCO, or so that it is performed at the very end of the sequence, after removal of the Boc-protecting group and functionalization as above-mentioned.

Compounds of formula Ib wherein X¹ is CH, X³ is NH, and Ar is 1,4-phenylene are prepared according to the method described in scheme 2:

Intermediate 3 is reacted with diphenylphosphoryl azide followed by reduction of the intermediate azide to provide amine 5. Reaction of amine 5 with isocyanate R²—NCO followed by Suzuki coupling with arylboronic acid R—B(OH)₂ affords biaryl urea 6. Then, and as for the end-synthesis of Ia, Boc removal with TFA and further functionalization of the resulting amine give biaryl urea Ib.

Compounds of formula Ic wherein X¹ is N, X³ is NH, and Ar is 1,4-phenylene are prepared according to the method described in Scheme 3 (m and n=1):

Reductive alkylation of piperazine 7 and 4-bromobenzaldehyde with titanium tetraisopropoxide and diethylaluminum cyanide affords Strecker amines 8a-b as a mixture of diastereoisomers. The Boc protective group in 8a-b is removed with TFA then the liberated free amine is functionalized via reductive amination with an appropriate aldehyde or ketone, or alkylation with an alkyl- or aralkyl-halide. The cyano group is then reduced with lithium aluminum hydride to give amines 9a and 9b that can be separated at that stage. Reaction of amine 9a and/or 9b with isocyanate R²—NCO followed by Suzuki coupling with arylboronic acid R—B(OH)₂, affords piperazine biaryl urea Ic-a and/or Ic-b that can also be separated at that stage. Separation of the diastereoisomers can be performed at any stage of the synthesis following and including intermediates 9a-b. Any modification of the sequence in the scheme including the use of other protective groups or simplification when starting from a non-protected amine 7 would be apparent to those skilled in the art.

Combinatorial libraries of compounds of formula Ib can also be prepared using solid phase chemistry as shown in Scheme 4.

A library of intermediates 20, prepared in a manner similar to intermediate 5 of Scheme 2, is treated with a suitable solid-phase aldehyde reagent 21 such as Novabiochem 2-(4-formyl-3-methoxyphenoxy)ethyl polystyrene in the presence of a reducing agent such as sodium triacetoxyborohydride to give resin-bound amine 22. This is treated either with an isocyanate 23a or with a carbamoyl chloride 23b optionally in the presence of a base such as diisopropylethylamine to give urea 24. The protecting group is removed by treatment with fluoride, and the resulting free amine 25 is derivatized as described in Scheme 1 and Scheme 2 to give 26. The product is removed from the solid support by treatment with strong acid such as trifluoroacetic acid. Modifications to the sequence, including the use of alternative protecting groups, will be apparent to those skilled in the art.

Alternative mechanistic pathways and analogous structures within the scope of the invention would be apparent to those skilled in the art.

MCH Receptor Binding Assay:

Membranes from CHO cells expressing the MCH receptor were prepared by lysing cells with 5 mM HEPES for 15 min at 4 C. Cell lysates were centrifuged (12.5000×g, 15 min) and the pellet was resuspended in 5 mM HEPES. For each 96-well plate (Microlite, Dynex Technologies), 1 mg of cell membranes were incubated with 10 mg of wheat germ agglutinin SPA beads (Amersham) for 5 min at 4 C in a volume of 10 ml of binding buffer (25 mM HEPES, 10 mM MGCl₂, 10 mM NaCl, 5 mM MnCl₂, 0.1% BSA). The membrane/bead mixture was centrifuged (1500×g, 3.5 min), the supernatant was aspirated, and the pellet was resuspended in 10 ml binding buffer. The centrifugation, aspiration and resuspension were then repeated. The membrane/bead mixture (100 μl) was then added to 96-well plates containing 50 μl of 500 pM [¹²⁵I]-MCH (NEN) and 50 ml of the appropriate concentration of compound (4× the desired final concentration). Nonspecific binding was determined by including 1 μM MCH in the binding reaction. The binding reaction was incubated at room temperature for 2 h. Plates were then analyzed in a TOPCOUNT microplate scintillation counter (Packard). Data was analyzed and Ki values were determined using GraphPad Prim.
